Fig. 33 is a plan view of the controller-keys and their operating mechanism with certain parts removed for clearness.

1 is the fixed frame of the machine, having suitable shape to support the different moving parts of the machine hereinafter described.

A machine of this character comprises a plurality ofcash-receptacles that are mounted side by side on a common axis. As the construction of the controlling and operating means is substantially identical for each such receptacle, I will herein describe only a single element, comprising a receptacle, the controller, which turns it forward in depositing or receiving the cash, and the operating means, whereby it is turned back to deliver the cash.

2 represents a shaft or axis on which the cash-receptacles are adapted to rotate independently. One of such receptacles is indicated at 3 and comprises a circumferential series of pockets formed by and between flanges, ribs, or Walls 3, said pockets being brought successively in the rotation of the receptacle opposite an opening formed in front of the casing 4. When the pocket is in this position, money may be charged into or ejected from it through said opening, and in the latter case such money is received on a ledge 6.

It is desirable to normally lock the cash-receptacle from movement in either direction except as it is rendered necessary by the cash receiving and delivering operations. To this end I provide two sliding dogs or catches 7 and 8, sliding in guides 9 and 9 on the under side of the ledge 6 before engaging, respectively, with the top and bottom of a rib or wall 3 of a cash-pocket, thereby preventing the cash-Wheel 3 from turning in either direction. Suitable springs engage the catches to normally throw them into position to engage the cash-wheel.

To turn the cash-wheel forward after cash has been deposited ina pocket, a controller is provided consisting of a key-lever 10, pivoted on a shaft 11, which is common to all the controllers, said lever having at its rear end a latch 13. adapted when the controller key or handle 10 is depressed to engage a rib or wheel 3 on the cash-wheel and turn the wheel one step forward to bring another pocket opposite and remove the last-filled pocket from accessible position. To enable this movement of the receptacle to be effected. the catch 8 must first be drawn back, and the controllerlever 10 carries a latch or tripping device If, that is normally held by a spring M in position to engage by its hook 14 with a lip 7 on the dog 8. (See Figs. 2 and 5.) \Vhen the controller-lever is pulled forward and downward, this latch draws the dog 8 forward to release the cash-wheel and allow the latter to be turned forward by the further movement of the controller, as above stated. In this further movement of the controller the latch 14 will be withdrawn from engagement with the dog 8 and allow the said dog to move forward and engage the next rib or pocketwall 3' of the cash-wheel. As the controller completes its movement this rib 3 strikes the inclined end of dog '7 and presses the same forward, said dog then snapping back below said rib 3, which is then locked between the dogs 7 and 8. Controller 10 when released by the operator is returned to normal position by a spring 17, pivoted to the lever and a portion of the ledge 6.

The means provided to move the cash-receptacle backward to deliver cash comprises an operator device or disk 20, mounted on the operator-shaft 21, said shaft being operated by a handle 25. A projection 22 on the operator-disk engages a rib 3 on the cash-wheel to turn the wheel backward, and another projection 23 thereon engages a lever 24, which operates a linger 24, which in turn engages a lip 7 on dog 7 to press said dog forward to release the cash-wheel for such backward rotation. In said rotation the next upper rib 3 of the cash-wheel passes the inclined end of the catch or dog 8, and the latter snaps back over the rib, as shown in Fig. 32.

The ejectment of money upon the ledge 6 is effected by the operating-shaft 21, which has mounted thereon a series of cams 30, adapted to engage an arm 31, pivoted on the ejector-shaft 32, which ejector-shaft in turn operates a series of ejector-arms 33, extending upwardly into the cash-receptacles in such position that when the ejector-shaft is rocked, by means of the cams 30, the ejector-levers will be moved forward in contact with any moneys that may be in the pockets that are exposed to the openings in the casing 4.

In some systems of coinage it is necessary that certain coins of the same denominational value, but of different sizes, be placed in the same cash-receptacle. hen such is the case, the quick forward movement of the ejectorlever is very apt to eject the coins in such manner and with such force that the lighter coin will bethrown over the coin-receiving ledge. In order to prevent such a condition, the ejector-lever is engaged by a spring-actuated arm 34, pivoted to an arm 35 dependent from the ledge 6, and is adapted to retard the action of the ejector-lever, so that the coins will be gently placed upon the ledge. Mounted on the ejector-shaft 32 are rock-arms 38, that have pivoted thereto ejector-arms 39, adapted to remove the surplus bills from the bill-receptacles when they are in excess of the required amount-that is, when the cash-receptacles have passed around to the position Where the ejector-arms 39 will engage the bill. (See F g- The operating mechanism for turning back the cash receptacle is mounted, as above stated, on the operating-shaft 21 and separate from the shaft carrying the controllers. As

the construction and operation of the controller-keys and their parts and the operator-disks and means for controlling the same to move the cash-Wheels are substantially identical for each controller-key, the following description will be of a single element comprising a controller-key, parts operatively controlled by it, an operator-disk, and the mechanism operatively connected therewith, this operating mechanism comprising a disk 15, fastened on the shaft 21 by a pin L6, an operator-disk 20, looselyv mounted on said shaft'and provided with a tooth or lug 22, adapted to engage'the rib or wall 3 on the cash-Wheel to effect the return movement thereof,and clutching means adaptedto connect the disks 4&5 and 20 when a cash-wheel is operatively' affected by the controllers and certain purchase-keys to be returned to deliver change. Said clutching means, Figs. 5, 6, 27, and 27*, consists of a plunger-pin 4E7, sliding in a hole 48 in disk 20 and pressed toward disk 45 bya spring 49, so as to force the end of said pin 47 into a hole or depression 50 in disk 45 when said hole isopposite the pin. The end of pin 47 and the depression 48 are beveled or rounded, so that as disk 20 starts to turn from this position it tends to cause the pin to ride out of the hole and disengage the clutch. A selector bar or plate 52 is guided by its slotted. portion 52,

sliding over the operating-shaft 21, and by its.

lower end engaging with and operated by the selector, as hereinafter more fully described.

I After the said selector-bar 52 has been lifted feeti-ng the disk 20. v On the disk 20 is a pin 55, that is adapted to engage a pin 56 on the selector-bar 52 when the selector-bar is down or in the position shown in Fig. 5. When the selector-bar is raised, as shown is Fig. 6, the pin 56 will be removed from the path of pin and allow the disk to rotate without engaging the pin on the selector-bar. Thus it will be seen that the disk 20 can only be operated to engage the cash-receptacles to move them to discharging position when the selector-bar 52 has been raised and the disk 20 has been freed from its engaging dog. Fig. 27 shows how the component parts comprising the disk 20 are secured together and loosely mounted on the shaft 21.

The means for controlling the operating mechanism for turning back the cash-receptacle consists of a series of dependent plates 60, mounted on a shaft 61, the said plates being engaged on their bottoms by forwardly-projecting arms 62, forming part of the operatordisk-engaging dogs 63, said dogs being loosely mounted on a shaft 64:. These disk-engaging dogs 63 are normally held out of engagement with thedisks by means of the dependent plates 60; but when abontroller-key is operated the upwardly-projecting cam-arm of the dependent plate 60 is engaged by a camroller 67, mounted on the controller-bar 10. When the controller-bar 10 is depressed, the roller 67 will engage cam-arm 65 and remove the plate 60 from engagement with the forwardly-projecting arm 62 and allow said dog to drop over the projecting lug 22 on disk 20. The dependent plates 60 have formed on their bottoms ears or lugs 60, which overlap each plate of lower denomination, so that when one of the controller-keys is depressed and the cam-arm 65 is operated by the controller-lever 10 to lift the dependent plate 60, corresponding to said controller-key, it will also lift all plates of a higher denomination and allow the dogs 63 to engage the disks 20 and prevent their rotation. The dependent plates 60 and the cam-arms 65 are preferably constructed in two parts-that is, the camarm is mounted on the shaft 61 and has a bifurcated portion 65, that engages the plate 60 to control its operation. In Fig. 5 the normal position of a dependent plate 60, a camarm 65, and a controller-lever is shown, and in Fig. 7 the same parts are shown in normal position and the dependent plate next above in denominational value and its controlling parts are shown as having been operated and a dog 63 thrown into engagement with the disk 20 to prevent its rotation. The depend ent plate to the extreme left of the machine, or the one attached to the controller-key of highest'denominational value, has connectedtherewith an arm 70, that is pivoted to an upwardly-projecting link 71, suitably guided at its bottom by means of a pin 72, held in a bracket 73, Fig. 25 and riding in a slot 7 1 in the link 71, Fig. 7. V

Suitably journaled in the supporting-frame of the machine just above the individual keylocking bars is a shaft 75, that has mounted thereon a bail 76, (see Figs. 2, 7, and 25,) that is adapted to engage shoulders 77 on the individual key-locking bars 100 to prevent the purchase-keys from being depressed until a controller-key has first been operated to give the link 71 a downward thrust, which will cause the stud 78, secured to said link, to engage an arm 79, mounted on shaft 7 5, and rock said shaft, causing the bail to be lifted out of engagement with the individual keylocking bars. At no time can a purchase-key be depressed until one of the controller-keys has been pulled down after making a deposit and the parts just described operated to disengage the hail from the individual key-locking bars.

To return the dependent plates 60 and the dogs 63 to normal position and allow the bail 76 to engage the individual key-locking bars to prevent their operation, a cam 80 is employed that is mounted on the operating-shaft 21 and adapted to engage a cam-roller 81, journaled' in an arm 82, that is secured to shaft 64. The shaft 61 has a longitudinal groove 64 therein, as shown in Fig. .30, in

Which freely ride projections 83, forming part of the dogs 63, as shown in Fig. 31. It will be noticed that after the dependent plates are moved to free the dogs 63 and said dogs allowed to engage the projections 22 on the disks 20 the lugs 83 Will be engaged by the lower surface 64: of the groove, so that when the arm 82 is lifted by the cam the shaft 64 will be rocked, carrying with it the dogs 63, lifting them out of engagement with the disks 20 and returning the projecting arms 62 of the dogs to allow the dependent plates to assume their initial position thereon. The roller 81 on arm 82 is held in constant engagement with the cam 80 by means of a spring 85, that is attached to the arm 82, the other end of the spring being secured to the machine-frame. The dependent plates 60 will by force of gravity resume their normal position. The arm 70 will be lifted, which in turn will raise the link 71 under the influence of a spring 71, Fig. 7, and remove the stud 78 from contact With the arm 79 on shaft 75, allowing the bail 76 to drop by force of gravity into engagement with the shoulder 77 on the individual key-locking bars to prevent the purchase-keys from being manipulated until a controller-key has been operated. The means for releasing the purchase-keys 84: from the individual key-locking bars after the keys have been depressed and restoring the individual key-locking, bars to their normal position will be hereinafter more fully described.

When the individual key-locking bars are free to allow the purchase-lwys 84: to be depressedthat is, after the bail 76 has been lifted in the manner hereinbefore described depression of any one of said keys will cause the lateral projection 87 on the edge of the key-bar to engage an inclined surface 89 on the side of the locking-plate and move said plate toward the rear of the machine until the projection 87 passes under and is engaged by a shoulder 90 on the locking-bar, in which position the key will be held until the operating-handle has been turned to cause the said key to be released from engagement with the individual key-locking bars. (See Figs. 7 and 8.) It will be noticed by referring to Fig. 8 that when a key is depressed and an individual key-locking bar has been moved rearward it will be impossible to depress any other key in that row owing to the fact that a shoulder or projection 100 will be in the path of the lateral projection 87 on the keybar and arrest the key before it could be depressed a sufficient distance to cause any operation of its coacting parts. This construction is found very necessary in order to prevent the possibility of the operator depressing two purchase-keys in the same row.

The purchase-keys are always depressed in order from the highest denomination down until the units-row is reached, where in this instance there are two keys, a 0 (indicated at 91) and 5, (indicated at 92,) either one of which in ustbe depressed toconclude a pu rchasc and to operate certainmcchanism which will release the operating-shaft to permit the operating-handle to be turned. This mechanism for releasing the operating-shaft is operated by either one of the keys shown in the units-row in the followingmanner: Suitably mounted on a stud 93, secured to the side of the machineframe, is an arm 9 the lower end of which is bifurcated, said bifurcations being engaged by lingers 95 and 96, forming part of sleeves 103 104, Fig. 26, loosely mounted on the 0 permutator-shaft 110, said sleeves being in turn controlled by the two keys in the unitsrow, (shown at 0 am 5, Figs 2 and 7.) hen one of the said keys is depressed, it will rock a sleeve 103 by reason of a stud 97 on said sleeve projecting through a slot 98 in the shank of the key, as shown in Fig. 7. This rocking of the sleeve on the permutator-shaft will cause the finger 95 to engage one of the bifurcations on the arm 94. and tilt said arm rearwardly, thereby engaging and moving with it adownwardly-projecting arm 99, pivotally supported on the ejector-shaft 32, which in turn will operate a pawl 101, that forms part of the arm 99 and projects above the ejector-shaft 32, and remove said pawl from engagement with a single-tooth disk 102, mounted on the operating-shaft, thereby freeing the operating-shaft to permit the operating-handle to be turned to complete an operation of the machine.

Suitablysecured in the frame of the machine is a number of permutater-shafts 110, that have loosely mounted thereon sleeves 105,
